陆旭老师，我有一些做过的assumption题目取非的句子搞不清，你能帮忙看下吗(不说这道题目的解题思路，单纯就是取非问题，特别是双重否定或者从句里面有否定词） 1.No part of a person’s brain that is damaged by a stroke ever recovers.---> some part of a person's brain that is damaged by a stroke ever recovers. 2.Impairment of linguistic capabilities does not occur in people who have not suffered any damage to any language center of the brain.这个句子我不太会取非，正过来说这个句子就是Impairment of linguistic capabilities occurs in people who have suffered any damage to any language center of the brain.那么我取非是Impairment of linguistic capabilities occurs in people who have not suffered any damage to any language center of the brain. 3.If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain damages at least one of them. 取非If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain damages nothing of them. 4.这题出现两个not The collection fee will not significantly affect the purchasing power of most residents, even if their households do not reduce the amount of trash they put out. 我取非直接去前面的not: The collection fee will significantly affect the purchasing power of most residents, even if their households do not reduce the amount of trash they put out. 5.这个也差不多 Not all steel producers were unaffected by country A’s newly imposed tariffs. 我取非All steel producers were unaffected bycountry A’s newly imposed tariffs. 6.There are no plants native to western Africa that, if domesticated, could serve as staple food crops. 这个if domesticated是不是可以不管，直接改成There are some plants native to western Africa that, if domesticated, could serve as staple food crops.

16题 ps 不太明白怎么算 感觉要求很复杂

想让老师用相关性方法讲一下

想让老师用相关性来解这道题

请问张慧雯老师，文章的句间逻辑关系写成这样子可以吗

老师能解释一下为什么A选项反驳了原文的论点吗

老师，我不理解A选项为什么不能反驳原文。原文的意思是评论家认为EI没有意识到自己有散光所以造成他的画作人物不正常的细长，那A选项的意思就是正是因为不能确定EI有没有意识到自己有散光，如果他意识到并去修复的话细长人物的风格就不是因为散光造成的。同时我也不懂D选项如何反驳了原文的解释

这题怎么做 没有思路

13题W为什么错？14题为什么说削弱三个假设就是与主旨相反的意思？我选了E不太明白为什么选A

为什么条件（2）可以整除2

请问may老师这道题的思路
